Patented Feb. 9, 1932 UNITED STATES JOSEPH MARKOWITZ, OF BROOKLYN, NEW YORK SEWER IPIPE CLEANING DEVICE Application filed March 7,

My invention relates to a new and improved sewer pipe cleaning device.

()ne of the objects of my invention is to provide a device for cleaning sewers, drains, or the like having an improved and adjustable handle which can be used for operating the cleaning member.

Another object of my invention is to provide a device of this type having a handle of very simple construction which can be gripped in order to firmly clamp the cleaning device and which can be released so as to he slid upon the cleaning device.

Another object of my invention is to provide a handle consisting of a pair of parts which are hinged together, the inner walls of these parts being so shaped as to cause the handle to normally remain in the open or inoperative position.

Another object of my invention is to provide a device which consists essentially of a pair of castings so'that the parts can be very readily assembled and the necessity for springs or the like, is eliminated.

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above general statement of my invention is inter led to generally explain the same and not to limit it in any manner.

Fig. 1 is a side elevation partially in section.

Fig. 2 is a sectional View on the line 2-2. of Fig. 1.

Fig. 3 is an enlarged longitudinal sectional view.

The cleaning device comprises a member 5 which is preferably made of stifl' but resilient steel and which can have a rectangular cross section.

A cleaning member H having spiral cutting edges is suitably ailixed to the front of this cleaning member 5.

The cleaning member 5 passes through a handle comprising members 1 and 2.

For convenience the member 1 can be called the top or outer member and the member 2 can be called the bottom or inner member, although the operation of the handle is inde- 1931. Serial No. 520,770.

pendent of the plane in which the same is used.

As shown in Fig. 2, the outer member 1 has the U-shaped cross section and the inner memher 2 has a substantially. rectangular cross section, said inner member 2 being formed with shoulders 2a at its longitudinal edges.

The strip 5 is located in the recess between the inner walls of said shoulders 2a.

The inner end of the outer member. 1 has a bolt B which passes through the flanges thereof and which also passes through a bore which is formed in the member-2. The bolt B is held in position by means of a nut 3 so that the member 2 is pivotally mounted upon the outer member 1.

As shown in Fig. 3, the front of the outer member 1 is formed with an offset clamping surface 8, and the corresponding end of the inner member 2 is formed with a curved and oflset clamping surface 8a.

This curved clamping surface 8a is eccentric with respect to the axis of the bolt B. Hence, when the operator forces the inner member 2 towards the outer member 1, as indicated in full lines at the right hand side of Fig. 1, the metal strip 5 is positively clamped between the handle members 1 and 2, so that the handle can then be utilized for pushing the strip5 forwardly.

When the operator releases the pressure of his hand, the inner member 2 is free to assume the position shown in Fi 3, and also in dotted lines in Fig. 1, so that the strip 5 is no longer clamped between the members 1. and 2, and it is easy to push the handle upon the strip 5, in order to clamp the strip 5 to the handle at another point of said strip.

The natural resiliency of the strip 5 also causes the inner member 2 to assume the inoperative position shown in Fig. 3.

A very simple, cheap and durable device is thus provided which does not require any springs.

WVhile the improved handle is particularly intended for use in pipe cleaning devices, it may be used for any other purpose.

The clcanin member 5 may have any desired shape. or example, it may be cylindrical in cross-section, as cleaning members of such shape are well known. Hence, the shape of the handle may be varied in accordance with the shape of the cleaning member.

I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions can be made without departing from its spirit.

I claim:

1. A handle comprising an outer member having an end provided with flanges, an inner member comprising a corresponding end located between said flanges, a pivot member passing through said flanges and through said inner member, said members having oifset clamping faces adjacent said pivot, one of said clampin faces being eccentric wit-h respect to said plvot.

2. A handle comprising an outer member having an end provided with flanges, an inner member comprising a corresponding end located between said flanges, a pivot member passing through said flanges and through said inner member, said members having offset clamping faces adjacent said pivot, one of said clampin faces being eccentric with respect to said plvot, said corresponding end of the inner member being formed with a longitudinal groove.

In testimony whereof I aflix my signature.

JOSEPH MARKOWITZ.
